For example, when a user is going to drive in the right direction (turn right), the user toggles or presses a button of driving in the right direction (turning right) on the motorcycle to activate a warning light. After a signal of the right direction indicator light is generated by the electronic control unit of the motorcycle, the electronic control unit may convert the signal from the CAN protocol into the communication protocol supported by the transceiver 130 , thereby generating the signal associated with the right direction indicator light.

For example, when the user is going to drive in the left direction (turn left), the user toggles or presses a button of driving in the left direction (turning left) on the motorcycle to activate a warning light. After the signal of left direction indicator light is generated by the electronic control unit of the motorcycle, the electronic control unit may convert the signal from the CAN protocol into the communication protocol supported by the transceiver 130 , thereby generating the signal associated with the left direction indicator light. If the dashboard application program 121 receives the signal associated with the left direction indicator light through the transceiver 130 , Step S 205 is proceeded. If the dashboard application program 121 does not receive the signal associated with the left direction indicator light through the transceiver 130 , Step S 201 is executed again.
  • the dashboard application program 121 may display a third configuration of the virtual dashboard 200 through the display 140 , wherein the third configuration may display a rear-view image corresponding to the left direction indicator light in a default area corresponding to the left direction indicator light. That is, in this step, because the user is going to drive in the left direction (turn left), the rear-view image of the left direction indicator light of concern is configured in the left half of the entire display area 210 in the original FIG. 3 A (that is, the default area corresponding to the left direction indicator light), so that when the user possibly turns the head slightly to the left to observe traffic conditions on the left side because of going to drive in the left direction, the configuration is in line with the action thereof and in line with the direction of vision or of deflecting the head.

 DESCRIPTION OF THE EMBODIMENTS
In order to make the content of the disclosure more comprehensible, the following embodiments are especially given as examples according to which the disclosure can indeed be implemented. Additionally, where possible, elements/components/steps using the same reference numerals in the drawings and embodiments represent the same or similar parts.
FIG. 1 is a schematic diagram illustrating a mobile device 100 according to an embodiment of the disclosure, wherein the mobile device 100 has a function of displaying a virtual dashboard, which can be used to replace a digital dashboard of a motorcycle. The mobile device 100 may include a processor 110, a storage medium 120, a transceiver 130, and a display 140. The mobile device 100 includes, for example, a smartphone or a tablet mobile device (pad).
The processor 110 is, for example, a central processing unit (CPU), other programmable general-purpose or special-purpose micro control units (MCU), microprocessors, digital signal processors (DSP), programmable controllers, application specific integrated circuits (ASIC), graphics processing units (GPU), image signal processors (ISP), image processing units (IPU), arithmetic logic units (ALU), complex programmable logic devices (CPLD), field programmable gate arrays (FPGA), other similar elements, or a combination of the above elements. The processor 110 may be coupled to the storage medium 120, the transceiver 130, and the display 140, and access and execute multiple modules and various application programs stored in the storage medium 120.
The storage medium 120 is, for example, any type of fixed or removable random access memory (RAM), read-only memory (ROM), flash memory, hard disk drive (HDD), solid state drive (SSD), similar elements, or a combination of the above elements for storing the modules or the various application programs executable by the processor 110. In this embodiment, the storage medium 120 may store modules including a dashboard application program 121, and functions thereof will be described later.
The transceiver 130 transmits and receives signals in a wireless or wired manner. The transceiver 130 may also execute operations such as low noise amplification, impedance matching, frequency mixing, up or down frequency conversion, filtering, amplification, and similar operations. The dashboard application program 121 may receive signals from an electronic control unit (ECU) and/or a dashboard camera of the motorcycle in the wireless or wired manner through the transceiver 130, wherein the signal may include a signal associated with a direction indicator light or a rear-view image, or may include dashboard information commonly seen on the motorcycle. The electronic control unit may be coupled to a sensor of the motorcycle to obtain sensing data. For example, the sensor includes, for example, a liquid level sensor disposed in a fuel tank of the motorcycle. The electronic control unit may output a signal for displaying a fuel level according to the sensing data from the liquid level sensor. The signal of the dashboard camera is, for example, a signal captured by an image capture device (e.g., a CMOS image sensor (CIS) or a charge coupled device (CCD)) disposed on the body of the motorcycle. In an embodiment, the signal of the electronic control unit and the signal of the dashboard camera may be integrated together or the hardware itself may be a single device. The transceiver 130 may communicate with the electronic control unit and/or the dashboard camera through a communication protocol supported by the transceiver 130, such as a Wi-Fi protocol, a Bluetooth protocol, or a universal serial bus protocol. Before transmitting the signal to the transceiver 130, the electronic control unit and/or the dashboard camera may convert a signal of a controller area network (CAN) protocol into a signal of the communication protocol supported by the transceiver 130.
The signal of the rear-view image may include a rear-view image corresponding to a right direction and a rear-view image corresponding to a left direction, wherein the rear-view image of the right direction may be similar to an image captured by a right rear-view mirror of the motorcycle, and the rear-view image of the left direction may be similar to an image captured by a left rear-view mirror of the motorcycle.
The dashboard information may include, but is not limited to, information such as engine malfunction diagnostic light, neutral indicator light and/or gear display, oil change indicator light, high beam indicator light, speed, rotational speed, fuel level, time, overrun light, and mileage.
The display 140 may include a liquid crystal display panel or an organic light emitting diode display panel (OLED), and the display panel may further be a twisted nematic liquid crystal display (twisted nematic-LCD) panel or a thin film transistor liquid crystal display (thin film transistor-LCD) panel. The dashboard application program 121 may display the virtual dashboard through the display 140. The virtual dashboard may be used to display information such as the direction indicator light, the rear-view image, or the dashboard information.
FIG. 2 is a flowchart illustrating displaying a rear-view image according to an embodiment of the disclosure, wherein the process may be implemented by the mobile device 100 shown in FIG. 1 . Assuming that the motorcycle is in a state of going straight at first, in Step S201, the dashboard application program 121 may display a first configuration of the virtual dashboard through the display 140, wherein the first configuration is a configuration displayed by the virtual dashboard in a case of going straight.
FIG. 3A is a schematic diagram illustrating a first configuration of a virtual dashboard 200 according to an embodiment of the disclosure. The first configuration of the virtual dashboard 200 may include a display area, an area 210. The dashboard application program 121 may display the dashboard information such as engine (or drive motor of an electric vehicle) malfunction diagnostic light, neutral indicator light and/or gear display, oil change indicator light, high beam indicator light, speed, rotational speed, fuel level (or battery level of the electric vehicle), time, overrun light, and mileage through the area 210. That is, the virtual dashboard 200 or the dashboard application program 121 is associated with information of operation of a vehicle or driving of the vehicle.
Returning to FIG. 2 , in Step S202, the dashboard application program 121 may determine whether a signal associated with a right direction indicator light is received. For example, when a user is going to drive in the right direction (turn right), the user toggles or presses a button of driving in the right direction (turning right) on the motorcycle to activate a warning light. After a signal of the right direction indicator light is generated by the electronic control unit of the motorcycle, the electronic control unit may convert the signal from the CAN protocol into the communication protocol supported by the transceiver 130, thereby generating the signal associated with the right direction indicator light. If the dashboard application program 121 receives the signal associated with the right direction indicator light through the transceiver 130, Step S203 is proceeded. If the dashboard application program 121 does not receive the signal associated with the right direction indicator light through the transceiver 130, Step S204 is proceeded.
In Step S203, the dashboard application program 121 may display a second configuration of the virtual dashboard 200 through the display 140, wherein the second configuration may display a rear-view image corresponding to the right direction indicator light on a default area corresponding to the right direction indicator light. That is, in this step, because the user is going to drive in the right direction (turn right), the rear-view image of the right direction indicator light of concern is configured in the right half of the entire display area 210 in the original FIG. 3A (that is, the default area corresponding to the right direction indicator light), so that when the user possibly turns the head slightly to the right to observe traffic conditions on the right side because of going to drive in the right direction, the configuration is in line with the action thereof and in line with the direction of vision or of deflecting the head.
FIG. 3B is a schematic diagram illustrating a second configuration of the virtual dashboard 200 according to an embodiment of the disclosure. Specifically, after the dashboard application program 121 receives a signal associated with a right direction indicator light 213, the dashboard application program 121 may divide the display area of the virtual dashboard 200 from the area 210 into an area 211 (which may be positioned on a left side of the virtual dashboard 200) corresponding to the left direction and an area 212 (which may be positioned on a right side of the virtual dashboard 200) corresponding to the right direction. The dashboard application program 121 may set the area 212 corresponding to the right direction as the default area in response to the received signal corresponding to the right direction, so as to display the rear-view image of the right direction through the default area. On the other hand, the dashboard application program 121 may display the dashboard information on the area 211 corresponding to the left direction. In other words, the image originally displayed on the larger area 210 may be reduced and displayed on the smaller area 211. In an embodiment, the dashboard application program 121 may fade an image displayed on the area 211, so that the rear-view image displayed on the area 212 is more prominent to help the user to focus on viewing the rear-view image.
Returning to FIG. 2 , in Step S204, the dashboard application program 121 may determine whether a signal associated with a left direction indicator light is received. For example, when the user is going to drive in the left direction (turn left), the user toggles or presses a button of driving in the left direction (turning left) on the motorcycle to activate a warning light. After the signal of left direction indicator light is generated by the electronic control unit of the motorcycle, the electronic control unit may convert the signal from the CAN protocol into the communication protocol supported by the transceiver 130, thereby generating the signal associated with the left direction indicator light. If the dashboard application program 121 receives the signal associated with the left direction indicator light through the transceiver 130, Step S205 is proceeded. If the dashboard application program 121 does not receive the signal associated with the left direction indicator light through the transceiver 130, Step S201 is executed again.
In Step S205, the dashboard application program 121 may display a third configuration of the virtual dashboard 200 through the display 140, wherein the third configuration may display a rear-view image corresponding to the left direction indicator light in a default area corresponding to the left direction indicator light. That is, in this step, because the user is going to drive in the left direction (turn left), the rear-view image of the left direction indicator light of concern is configured in the left half of the entire display area 210 in the original FIG. 3A (that is, the default area corresponding to the left direction indicator light), so that when the user possibly turns the head slightly to the left to observe traffic conditions on the left side because of going to drive in the left direction, the configuration is in line with the action thereof and in line with the direction of vision or of deflecting the head.
FIG. 3C is a schematic diagram illustrating a third configuration of the virtual dashboard 200 according to an embodiment of the disclosure. Specifically, after the dashboard application program 121 receives a signal associated with a left direction indicator light 214, the dashboard application program 121 may divide the display area of the virtual dashboard 200 from the area 210 into the area 212 corresponding to the left direction and the area 211 corresponding to the right direction. The dashboard application program 121 may set the area 212 corresponding to the left direction as the default area in response to the received signal corresponding to the left direction, so as to display the rear-view image of the left direction through the default area. On the other hand, the dashboard application program 121 may display the dashboard information on the area 211 corresponding to the right direction. In other words, the image originally displayed on the larger area 210 may be reduced and displayed on the smaller area 211. In an embodiment, the dashboard application program 121 may fade the image displayed on the area 211, so that the rear-view image displayed on the area 212 is more prominent to help the user to focus on viewing the rear-view image.
FIG. 4 is a flowchart illustrating a method of displaying a rear-view image of a vehicle (e.g., a motorcycle) according to an embodiment of the disclosure, wherein the method may be implemented by the mobile device 100 shown in FIG. 1 . In Step S401, a rear-view image is received. In Step S402, a virtual dashboard is displayed through a display. In Step S403, the rear-view image is displayed on a default area of the virtual dashboard in response to receiving a signal associated with a direction indicator light, wherein the default area corresponds to the direction indicator light. In an embodiment, when Step S401 or Step S402 is activated, a function of charging the mobile device 100 is activated at the same time. The function of charging may charge the mobile device 100 through a wired or wireless charging device configured on the motorcycle, so as to ensure that the mobile device 100 has sufficient electric power to continue implementing the method of displaying the rear-view image on the vehicle.
In summary, the mobile device of the disclosure can display the rear-view image of a direction for the user to view when the user intends to turn or switch lanes in the direction, so that the user can timely grasp the situation of vehicles coming from behind. In addition, to cooperate with the turning direction that the user is going to drive, the rear-view image of the turning direction of concern is configured on the area that is inclined to the corresponding turning direction, which is in line with the direction of vision or of an action such as deflecting the head to facilitate driving safety. The mobile device may change a panel surface of the virtual dashboard to display the rear-view image and may enable the displayed rear-view image to be more prominent through manners such as fading the image. By replacing the digital dashboard of the motorcycle with the mobile device, in addition to reducing the production and manufacturing costs of the motorcycle, and saving the cost of maintaining the digital dashboard for the user, an accommodation place with an easy access for the mobile device when driving is also provided for the user to meet the requirements of modern people who are accustomed to carrying mobile devices with them.
